Is MJF Suitable for Production Parts? A Practical Engineer’s Guide

Why Engineers Choose MJF for Production Parts MJF didn’t rise just as a prototyping machine. It climbed straight into real manufacturing. The making of HP Multi Jet Fusion 3D printed parts uses a fine-grained nylon powder fused with a chemical fusing agent and precision infrared heating. That means consistent, repeatable parts without visible stepping or layered fragility. Dimensional accuracy typically sits around ±0.2 mm for small features, depending on geometry, orientation, and part size, tight en......

Which Resin Is Best for 3D Printing Fine Details vs Functional Parts?

Resin 3D printing is often marketed as a single category, but in practice, the resin you choose matters more than the printer itself. A photosensitive resin optimized for ultra-fine surface detail behaves very differently from a resin designed for load-bearing or heat-resistant parts. Treating them as interchangeable is one of the most common reasons resin prints fail to meet expectations. When comparing 3D printing resin types, the real question isn’t which resin is “best” overall, it’s what the part......
